SANS internet Storm Center said the problem stems from the Apache Connector used by the products. A WebLogic advisory noted the flaw could be exploited without authentication.

Moore detailed what happened on a blog post at Metasploit. The incident hit an AT&T DNS cache server; the affected machine coincidentally served "as an upstream forwarder for an internal DNS machine at BreakingPoint Systems," which is Moore's company.
"This attack affected anyone in the Austin, Texas region using that AT&T internet Services (previously SBC) DNS server. The attack itself was not malicious, did not load malware, and from an operational standpoint, had zero impact," said Moore.
